4 out of 5 eggsCool and Silent!

Pros: I have two of these running in one machine to split the load. One power supply is plugged into the 24 pin ATX plug and the other runs everything else (see Other Thoughts).

I was worried they would run hot and heat up the inside of the case but that is not the case. These things work flawlessly and are completely cool to the touch at idle or light use. Running Prime95 for 30 minutes results a slight warming but no more than a normal fanned power supply.

Running two of these I get the best of everything, quiet, cool and they don't even break a sweat. I'm hooked!

Cons: Hated to knock of an egg but the wiring coming out of the unit is a big tangled mess. Sleeving starts about 3 inches outside the power supply leaving the colored wires in plain sight, very unprofessional.

Expensive.

Other Thoughts: In my machine, two of these power supplies are running:

Core i7 975 Extreme
4 SSD's (RAID 0)
7 Raptor 150's (RAID 5)
2 1TB WD Blacks (RAID 1)
Areca 1321ML
12GB Crucial 1066 Memory
Sapphire HD 5750
Xonar Essence STX
Intel NIC card
DVD Burner
6 - 140mm 900 rpm case fans
2 - 120mm fans

Windows 7 Professional
VMWare Workstation

5 out of 5 eggsHigh Quality PSU

Pros: Well made. Quality parts. Noiseless, even under load. Enough power for most builds.

Cons: None

Other Thoughts: This is my second one. First one working great in my HTPC. This one is going in my DAW along with all SSD's for a totally silient build.

5 out of 5 eggsSimply fantastic

Pros: Wonderfully silent PSU that can truly deliver >400W on a continuous basis, without a hiccup. Truly one of my best computer-related purchases, ever.

Cons: It's not yet available in a 1200W version!

Other Thoughts: This is one of those TRULY RARE computer-related purchases that absolutely & completely works as advertised. It's been a complete joy...so I bought two of them! I'm presently using one for my main home office PC, and it is flawlessly (& silently) powering: an Asus P6T7 WS SuperComputer MoBo; 6GB G.Skill 1333 DDR3; Core i7-920 @ 2.8GHz; 3xGigabyte Silent Cell 9800GTs (one gets its supplemental power from a dual-molex-to-6-pin-PCIE adaptor); Asus Xonar D2X; Zalman MFC2 fan controller; LG Super Multi Blue drive; 5xSSDs in RAID0; & 7 fans, all in an Antec P190.

I'm using these 3 particular GPUs so as to contribute to the Folding@home effort as much as I can...while remaining SILENT so as not to disturb anyone. At any given typical moment, this system is drawing just about 397W (as reported so conveniently on the Zalman ZM-MFC2). It runs 24/7 with complete stability...and again, SILENTLY. This is one of VERY FEW computer products I can wholeheartedly recommend to you!

5 out of 5 eggs0db!

Pros: Quiet. Good cable management options. Plenty of connection feeds.

Cons: Price.

Other Thoughts: Price is high but the result is the real deal. 0db, no fan noise. PSU fans after months of use always seem to be one of the biggest culprits of noise. This is no longer an issue.

5 out of 5 eggsPrecious metal

Pros: This is a large chunk of aluminum. The entire unit is one big heavy heatsink.

Perfectly quiet and seems to work just fine.

Cons: Proably not a good idea to use this PSU in a case with lots of hot components. I used a very low power CPU and HD and everything is very quiet and cool.

Be careful about case ventilation. Usually, the PSU unit helps to pull hot air out of the case. Also, there's usually a rear case fan that also exhausts hot air out of the back. This creates a negative pressure condition inside the case and promotes good airflow.

However since this PSU does not actively move any air, you would do well to pressurize the case by reversing the rear case fan so that it blows into the case. Pressurizing the case results in some airflow being forced out of the PSU. This is what I did and I hope this makes sense.

The bottom line is that it would be a good idea to make sure you have more fans blowing air into the case rather than sucking air out. This will force air out of the power supply and keep everything happy.

Other Thoughts: Purchased this as part of a recent build for my father.
